Definitions

  • the present invention relates to an improved fluid dispensing system for projecting finely divided particles of solvent onto a windshield for wetting the vision area of a windshield and to an improved discharge nozzle for such a system.
  • the wetting agent In order to efficiently clean a Windshield, it is essential that the wetting agent remain suspended on the windshield in advance of the blade until the blade sweeps across the portion to be cleaned.
  • the contacting rubber wiping lip becomes more efiective in acting to scrub off the grime.
  • the separated particles provide sufiicient surface friction between the wiper element and the wetted glass to produce a component of blade cling for obtaining optimum scrubbing action.
  • a system which projects a solid stream onto the windshield, requiring fluid distribution across the vision area by blade action hinders the scrubbing effectiveness of the blade during the period in which the blade is acting to distribute the fluid.
  • Fully distributed wetting of the surface to be cleaned further tends to dissolve or loosen the grime in advance of scrubbing by the blade.
  • a wetting pattern which covers the entire vision area of the windshield with finely divided particles of non-aerated solvent separated from each other is desirable. These fine particles cling to the glass due to surface tension and remain separated to provide improved vision until they are merged by the sweep of the blade which thereby Was es and wipes the surface dry. Such a distribution of particles conserves the wetting agent and eliminates the need of prolonged dry wiping.
  • the windshield cleaning system of the present invention with its improved nozzle is highly eliective in providing a discharge of r'inely divided non-aerated fluid particles and even a single cycle of wiper operation has been found highly effective to produce cleaning of the surface of dust and light deposits of grime from wheel spray. This is accomplished with a single centrally located nozzle. Furthermore, with the improved nozzle of the present invention, clogging of the nozzle is eliminated because the nozzle remains in its normally closed position, preventing accumulation of foreign substances in the orifice when the washer is not in operation. Because the nozzle accumulates solvent under substantial pressure prior to discharge, when discharging it becomes self-cleaning due to the high pressure under which solvent is ejected and to the relatively large opening of the jet in its distended position. The vibrating action of the orifice during operation causes the break-up of the fluid into line particles.
  • the principal object of the present invention is to provide an improved washer system which projects onto a windshield a wide fan-shaped spray pattern of finely divided deposits of washer solvent separated from each other so that vision during the Wetting operation is not obscured.
  • Another object of the invention is to provide an improved washer system utilizing a high pressure pump and a pressure accumulating nozzle which is caused to vibrate by action of repeated pressure accumulation and subsequent solvent discharge during each cycle of pump operation.
  • a further object of the invention is to provide an improved washer system which projects finely divided particles of washer solvent onto the entire visual area of the windshield utilizing only a single nozzle which particles remain separated and suspended on the surface of the windshield due to surface tension and which become merged only by the blade travel across the wipe pattern and disappear.
  • FIG. 1 is a partial perspective hicle incorporating the invention
  • FIG. 2 is a sectional view taken on line 11-11 of FIG. 3 illustrating the nozzle of this invention
  • FIG. 3 is a front elevational view of the nozzle assembly of this invention.
  • FIG. 4- is a bottom elevational view of the nozzle asembly of this invention.
  • FIG. 5 illustrates a coordinated windshield washer control incorporating one form of pumping element which may be utilized with the present invention
  • PEG. 6 is a partial perspective view of a motor vehicle incorporating the washer system of the present invention utilizing another form of pumping unit;
  • FIG. 7 illustrates another form of pumping unit which may be utilized with the washer system of this invention.
  • the washer system of this invention comprises a reservoir, a unique discharge nozzle, a pump and conduit means connecting the reservoir, the pump and the discharge nozzle.
  • the discharge nozzle is a tubular member having a closed end with a transverse opening elastically biased to a normally closed position.
  • the body portion of the tubular nozzle has thickened wall portions to more firmly bias the transverse opening to its closed position.
  • the vibrations break up the fluid into finely divided solvent particles which are projected onto the windshield and remain suspended thereon separated from one another by surface tension until merged by the travel of the wiper blades. Particles are distributed over the entire vision area of the Windshield due to the elongate shape of the orifice and the high pressure at which they are projected.
  • FIG. 1 there is shown a partial view of a motor vehicle 10 having mounted thereon a windshield 12 in a conventional manner.
  • the motor 14 is shown by way of example as being an electric motor, but any suitable or desirable type of motor as, for example, hydraulic or vacuum may be employed.
  • a control 16 is mounted on the vehicle dashboard and is connected by suitable electric circuitry to the motor 14 for energizing the motor.
  • a suitable linkage system 18 is provided for transmitting motion from the wiper motor to a pair of wiper arms 20 in a conventional manner.
  • the wiper arms 2% mount wipers 22.
  • wiper motor 14 is placed in operation and causes wipers 22 to oscillate back and forth across windshield 12.
  • the particular pump illustrated is described ain detail in application Serial No. 269,654 by John R.Oishei and Martin Hitzer, filed April 1, 1963.
  • This pump is coordinated with the wiper motor control 16. Through the use of a force multiplying lever 3t), fluid is projected at relatively high pressure while at the same time switch 32 is operated to energize the wiper motor.
  • the intake port of the pump is connected through a conduit 34 to reservoir 26 and the discharge port of. the pump is connected through a conduit as to the discharge nozzle assembly 23.
  • a single nozzle assembly 28 located substantia.ly centrally on the cowl is employed.
  • a pumping mechanism is shown and described for the purpose of illustration, in accordance with the broadest aspects of the invention, other and different suitable high pressure pumping mechanisms may e utilized.
  • the nozzle assembly 28 comprises a tubular conduit 36 extending through a central portion 33 of the cowl of the vehicle.
  • the conduit 36 is suitably angled at 4-8 to provide a downwardly directed portion 42 and an outwardly directed portion 44.
  • the outwardly directed portion extends upwardly and toward the windshield.
  • the tubular conduit 36 is provided with a suitably formed coupling portion 46 for fluid tight connection to conduit 36.
  • the conduit 36 is formed with an enlarged portion-48 of substantially spherical configuration.
  • the nozzle assembly 28 includes a nozzle 5d of rubber-like elastomeric material.
  • the nozzle 50 is of substantially tubular form and has a closed end 52, which may be of curvilinear configuration, with a transverse slit 54 therein forming lips 56 and A tubular body portion 69 has side walls of greater thickness than the thickness of the lips 55 and 5% to provide a greater biasing force for biasing the lips 56 and 58 to close the slit 54.
  • the enlarged portion 48 of conduit 36 is of larger diameter than the inner diameter of the body portion 69 of nozzle 50. This provides a force fit between the nozzle 5t? and the conduit 35 to prevent the nozzle from becoming disengaged therefrom when pressure is built up within the nozzle assembly. This enlarged portion also enhances the biasing efiect to maintain the slit 54- in its normally closed condition.
  • a shield 62 which encloses the nozzle 51) and includes flared side walls 64 and 66.
  • the disposition of the housing with respect to the nozzle 59 may be adjusted to control the solvent projection pattern.
  • the shield 62. is knurled on its lower side which lies adjacent the cowl of the vehicle to prevent displacement thereof.
  • Disposed intermediate the housing 62 and the adjacent cowl portion of the vehicle is a resilient washer 66 and on the underside of the cowl is a suitable push-on t"pe fastener 63 for maintaining the nozzle in position on the cowl.
  • the particles are projected in a fan-shaped pattern encompassing the entire vision area of the windshield with the particles disposed separated from each other. Because of the extremely small dimensions of the particles, they remain suspended in position on the windshield without merging and without drain-back until they are caused to merge by travel of the wiper blades. It can be seen that an extremely small amount of fluid is required during each cleaning operation because the particles are of small dimensions and widely distributed.
  • FIG. 6 Another example of a pump is shown in the embodiment of the invention illustrated in FIG. 6 wherein a pump of the type described in detail in Patent No. 3,097,608 by R. A. Deibel and W. C. Riester, issued July 16, 1963, is ultilized.
  • the pump 24 of this embodiment is a type which operates in repeated cycles so long as the control 16 remains in the on position.
  • FIG. 7 A still further form of pump is shown in FIG. 7 and is described in application Serial No. 304,431 by Anthony R. DAlba filed August 26, 1963.
  • This is a springless type pump 7% actuated in one direction by a movable element or cam 72 on the output transmission system of the wiper motor.
  • the cam is mounted on the output shaft 74 of the wiper motor 76.
  • the cam drives a piston rod or plunger 78 on its discharging stroke which moves a piston, not shown, to discharge fluid through a discharge conduit 30.
  • An energy actuating biasing source provides a force to return the piston and to bias it against the cam 72 with spring-like action on the intake stroke whereby fluid is drawn from the reservoir through intake conduit 82.
  • the energy source for biasing the piston on an intake stroke may be a vacuum source communicating with the pump housing 84 through a conduit 86 and a port 38.
  • a solenoid or other source of energy for producing a force in the direction of the intake stroke may be utilized in accordance with the broadest aspects of the invention.
  • a nozzle assembly for discharging finely divided particles over a relatively Wide area of a Windshield comprising a conduit, a nozzle of elastomeric material mounted at the end of said conduit and means for sheltering said nozzle to protect against nozzle maladjustment, said nozzle including a tubular body portion and a closed end portion, said means for sheltering being open adjacent said closed end portion of the nozzle, said closed end portion of the nozzle having a substantially transversely extending slit of a length sufiicient to provide wetting of substantially the entire Wiping pattern, said nozzle being normally biased to closed position and said slit being open When subjected to increased fluid pressure, said conduit having an enlarged diameter adjacent said end, said enlarged diameter being of greater dimension than the inner diameter of said tubular portion for retaining and stressing said nozzle to effect biasing of said slit to closed position and said conduit being of material and relative to said nozzle.
